Abstract

The utility model discloses a connecting structure for connecting steel beams to concrete stairs, which is arranged among the steel beams and the reinforcing steel bars of the concrete stairs. The connecting structure comprises at least an angle iron, wherein each angle iron comprises a bottom surface and an oblique surface, an included angle is formed between the bottom surface and the oblique surface, the bottom surface is fixedly connected with the steel beams, and the oblique surface is fixedly connected with the reinforcing steel bars of the concrete stairs. The requirements of the building structure design are satisfied, the integral structural rigidity is guaranteed, and the quick connection of the steel structure and the concrete stairs can be realized. By utilizing the connecting structure, the construction process can be simplified, and at the same time, the butt joint of the steel structure and the concrete structure, which have different properties, is ensured to conform to the strength requirement.

Description

Be used to connect the syndeton of girder steel and concrete staircase
Technical field
The utility model relates to building structure field, relates in particular to a kind of be used for realizing industrial premises, civilian steel house concrete and steel beam web plate connection structure connecting.
Background technology
Over nearly 20 years, the achievement of China's reform over 30 years progressively embodies, and along with the enhancing of national power and the fast development of national economy, China has become the industrial power that World Economics is had material impact gradually, rises sheer from level ground in large quantities of new industrial parks.Wherein open policy has played huge facilitation to Chinese industrial expansion, and new technology and a large amount of advanced technology resources are taken the lead in introducing by many large-scale domestic enterprises.Produce needs for satisfying, satisfy the special process requirement,, in a lot of steel houses, require stair must be concrete structure as the fire-protection rating requirement.Therefore the problem of having brought steel work and concrete structure how to be connected.This is because in the existing building structure, institute's employing steel work is connected with steel work, realize that steel work and steel work ways of connecting are various and flexible, technology is comparative maturity also, and once change steel work into and be connected with concrete structure, will bring the difficult problem on many engineerings.
Summary of the invention
The purpose of this utility model provides a kind of syndeton that is used to connect girder steel and concrete staircase, this structure is satisfying the fabric structure designing requirement, when guaranteeing overall structure rigidity, can realize that steel work is connected with the quick of concrete staircase, use this structure can simplify work progress, guarantee that simultaneously docking between these two kinds of structures of different nature of steel work and concrete structure meets requirement of strength.
According to the foregoing invention purpose, the utility model provides a kind of syndeton that is used to connect girder steel and concrete staircase, it is located between the reinforcing bar of described girder steel and concrete staircase, this syndeton comprises: at least one angle steel, described angle steel comprises a bottom surface and an inclined-plane, being an angle between described bottom surface and the inclined-plane, fixedlys connected with girder steel in described bottom surface, fixedlys connected with the reinforcing bar of concrete staircase in described inclined-plane.
Preferably, the described syndeton that is used to connect girder steel and concrete staircase comprises two angle steel, described two angle steel are first angle steel and second angle steel, wherein fixedly connected with the middle part of girder steel in the bottom surface of first angle steel, the parallel reinforced steel bar setting of the inclined-plane of first angle steel and concrete staircase, and fixedly connected with the soffit of the reinforcing bar of described concrete staircase; Described second angle steel the bottom surface fixedly connected the parallel reinforced steel bar setting of the inclined-plane of second angle steel and concrete staircase, and fixedly connected with the upper surface of the reinforcing bar of described concrete staircase with the upper end of girder steel.
Preferably, described each fixedly connected being is welded to connect.
The utility model is owing to adopted above technical scheme, make it compared with prior art, have the following advantages and good effect: its syndeton is simple, can realize the rapid abutting joint of girder steel and concrete staircase, and the assurance bonding strength, it satisfies country fully to the fabric structure designing requirement, has guaranteed overall structure rigidity, adopt this syndeton to construct simultaneously, work progress is simply quick.
Description of drawings
Fig. 1 is the annexation schematic diagram of concrete staircase and girder steel in the building structure.
Fig. 2 is the syndeton schematic diagram of girder steel and concrete structure in the present embodiment.
The specific embodiment
As shown in Figure 1, in the steel framed structure house, the stair 2 that are obliquely installed will be realized realizing meeting being connected that engineering strength requires with horizontally disposed girder steel.
As shown in Figure 2, for being connected of each piece girder steel and concrete staircase, all realize by two blocks of angle steel.Wherein girder steel is an i beam 1, and stair 2 are obliquely installed, and stair reinforcing bar 21 is as the skeleton that supports concrete staircase 2.First angle steel 3 among two blocks of angle steel, the middle part of its bottom surface and i beam 1 is welded to connect, and the soffit of inclined-plane and stair reinforcing bar 21 be arranged in parallel, and is welded to connect with the soffit of stair reinforcing bar 21, and the bottom surface of first angle steel 3 and the angle between the inclined-plane are acute angle.The bottom surface of second angle steel 4 is erected on the upper surface of i beam 1, and be welded to connect with it, the upper surface of the inclined-plane of second angle steel 4 and stair reinforcing bar 21 be arranged in parallel, and is welded to connect with the upper surface of stair reinforcing bar 21, and the bottom surface of second angle steel 4 and the angle between the inclined-plane are the obtuse angle.The bottom surface of first angle steel 3 and second angle steel 4 all equates with the bench width of stair with the length on inclined-plane.
Be noted that above enumerate only for a specific embodiment of the present utility model, obviously the utility model is not limited to above embodiment, and many similar variations are arranged thereupon.If those skilled in the art all should belong to protection domain of the present utility model from all distortion that the disclosed content of the utility model directly derives or associates.
